RICHARD MURDOGK, OF BALTIMORE, MARYLAND.

MACHINERY FOR PRESSING BONN ETS, &o.

Specification of Letters Patent No. 2,817, dated October 12, 1842.

To all 'whom t may concern.'

Be it known that I, R101-IARD MURDoC-K, of the city of Baltimore andState of Maryland, have invented new and useful Inr provelnents on myPatented Machinery for Pressing Bonnets, Hats, and other Articles V andfor other Uses, which is described as follows,`reference being had tothe annexed drawings of the saine, making part of this specification.

Figure l is a perspective view of the machine; Fig. 2, vertical `sectionof the post, seat and spindle; Fig. 3, horizontal section of the hub andarms l, 2; Fig. 4, section of thepostshaft and seat for holding theblock in a horizontal or inclined position; Fig. 5, perspective view ofthe frame, convex table, vibrating table, &c.; Fig. 6, perspective viewof a frame convex and concave box iron, rod and weight, pulley cord andweight; Fig. 7, another modication of the frame;l Fig. `8, shows theweight and spindle attached rising and falling together; Fig. `9,stirrups and post connected.

The frame, lettered A, is composed of a stout piece of timber of therequired size-- say about two feet long and 4t or 5 inches thick placedin a horizontal position hav ing another horizontal timber A2 of thesame thickness but of less length mortised and tenoned into the samenear one end thereof. A post A3 is let into the last mentioned timber A2and fastened with a wedge or in any convenient way.` This `post isslitdown the center thereof from the top to near the bottom forming arectangular' inortise C into which is placed a metallic seat D havingtwo trunnions E at the upper end thereof on which it turns in theaforesaid mortise-said trunnions turning on the head of the post, Thisvibrating seat is made open in the center or perforated with an oblongmortise F.` Itis also perforated vertically with a round aperture forthe admission or insertion of a vertical spindle Gr. T he aforesaidvibrating seat D is' for the purpose of allowing the block on which thebonnet to be pressed is placed and which block'is put on the spindle toadapt itself to the various changes of the pressing iron. The spindle Gris nearly twice the length of the postand of any required diametertapered at `the lower end where it is inserted into a step or cavityformed in the seat.

The upper end G2 of the spindle'is made altered in various ways.

separate from the main body thereof so that it can be taken off andremoved when it is required to lower the block to adapt itself to theheight of the pressing iron and for this purpose it is perforated in themiddle for l the insertion of a dowel pin which fits into acorresponding aperture in the head of the spindle. Or the height of theblock may be On this spindle near the middle thereof is fixed ahorizontal bevel wheel H with three or more radiating arms `I forturning it by hand but it may be turned by a vertical bevel wheel J into`which it works lixed on a horizontal crank shaft K turning in boxes orears on a plate L screwed to the post. Said bevel gear or arm, or crankis for thepurpose of turning the hat block horizontally during theoperation of pressing the bonnet on the block `resting upon the bevelwheel and kept from ,turning round on the spindle by a ver-tical pin Mrest-ing upon the bevel wheel and entering the block. When it isrequired to retain the spindle in a vertical position a pin N isinserted horizontally through the post and seat which holds it securely.Only one `cap is required for one trunnion the other `being helddown bythe end of the crank shaft K entering the cavity in the outer end of thetrunnion. These trunnions, as before stated are for giving the seat withthe spindle and block a movement in the open post; andthis Iconsider asone of my im rovements with the arrangement of the radiating arms I onthe bevel wheel for turning the spindle andblock.

The iron O for ironing the bonnet is made hollow and is called a boxiron. One of its sides O2 is hinged so that it can be opened to admitthe hot iron or heater for heating `the box. And when the heater isinserted said hinged side is shut down and secured by a catclrorfastened in any convenient way.

A round stud P projects from the top of the box and passes through acorresponding round aperture in a cast iron frame Q fastened to the'endlof theV lever R and through the part of the stud projecting through the`frame a pin is inserted above a washer for holding the parts togetherand to allow the box to have suflicient play and in order to give thebox still more play the stud is made tapering and theaperture oblong.

A catch S is attached tothe side of the its convex face is used.

horizontally in a transverse position it is held in that` position by avertical pin passed through the frame and into the box.

A counter weight U is fastened in the outer end of the iron frame Q, ofthe lever containing the box, in an upright position when the box ishorizontal. The weight receiver V2 for containing the weight for givingthe required pressure is attached to the end of the iron frame Q of thelever R to which the counter weight U is attached by means of a doubleperforated curved stirrup l/V and loose joints.- In the center of theweight receiver which in this modification of the invention is acircular platform with a circular curb or rim X having in its center acast iron perforated flanged hub Y with two arms 1, 2, F ig. 3,projecting therefrom to the outer extremity of one of said arms (1) thelower end of the stirrup W is attached a loose joint m the upper end ofsaid stirrup being attached to `the counter weight U lon the end of theiron frame Q, by a similarly constructed joint. The plate form V2 restsupon the flange 0f the hub. From the Center .0f the last mentioned arm'there rises a post 3 perforated with a number of holes into which isinserted a pin l for retaining the weight at any given height in themanner to be described. The weight holder V2 is guided in its verticalascent and descent by a round post or spindle 5 inserted into the frameof the machine.

The stirrups are perforated with a segment row of apertures 6 for theinsertion of pins that come against the sides of the post 3 rising fromthe arm 1; or one of said pins may pass through the post and stirrup forconnecting them together.V In Fig. 1 these are represented as separated.

The pin t inserted through the perforated post strikes upon the head ofthe spindle 5 which governs, the descent of the weight upon which post apiece of leather 7 is placed on the' head of the spindle to lessen thejar and noise.

The aforesaid manner ofv attaching the weight of the lever of the boxiron by means of the curved jointed stirrup W and hub Y moving over thevertical round spindle 5 on which the weight turns horizontally andrises and falls vertically allows the box to be moved in almost everi7possible direction y around-'and over the bonnet to be pressed with thegreatest ease and facility the weight rising and falling onl the spindleas the box is passed over the bonnet by raising and depressing the leverand allowing it to turn horizontally on the spindle as the lever is.turned to the right and left.

The above described mode of attaching the box iron to the lever and ofweighting the same and of adjusting the rise and fall of the Weightconstitutes another important improvement in the machine.

The shaft 8 for retaining the bonnet blocks in a horizontal or inclinedposition for pressing the sides of the crowns and the V the fronts whenthe bonnets are in one pieceand for vother uses is arranged and turnedin the following manner.V A horizontal timber At. is connected to thebefore described frame bymeans of an eye bolt 9 and turning wedge 10.From this timber, rises a post 11 attached to the horizontal timber byan eye bolt screw and nut and wedge bolt. In this post 11 is made amortise 1 2 to admit the seat of the shaft 8 which has a movementtherein for adjusting the same.` The seat consists of a right angledcasting 1 3 one branch of which 14; being vertical and the other 15horizontal whenl the shaft is to lie horizontal. This right-angledcasting or Y seat turns on a horizontal pin 16 passed` through the samenear the lower end of its vertical limb and an ear 17 projecting from acasting 18 screwed to the side of the postV which serves as a fulcrum.At the'angle of the casting or top of its vertical limb is a mortisewith dovetailed sides in which is placed a block 19 with correspondinggrooves on its sides in which block is formed a semicircular depressionin which the shaft 8 turns. T o the outer end of the horizontal arm o fthe seat is attached `by mortise and tenon a vertical casting 20 inwhich is made a round aperture to admit the outer end of the shaft 8 toturn therein, By raising or lowering this end of the horizontal arm 15.the angle of inclination of the shaft 8 Yis the shaft. A circular plate26 with its periphery brought to an edge is fixed to the other end ofthe hub; sockets are formed on the outside of this plate to receive theends of corresponding arms 27 or levers inserted therein for turning theblock by hand. Two

projections or cog's 28 are fastened to two of the arms for enteringcorresponding cavities in the end of the bonnet block e for preventingit from turning on the shaft 8 and
